Senior Backend Engineer - Investment Technology

We are looking for a senior backend software engineer to join our core service API team within Investments Technology. Our team designs, builds and operates the core services and APIs that are used across Investments Tech applications, supporting portfolio managers, analysts, and traders across Equity, Fixed Income and Multi-Asset. In this role you will design, develop, modify, adapt and implement short and long-term solutions that enhance and expand these shared services.

Principal Responsibilities

Delivery:

Delivering new core services and API capabilities, primarily in Java and C#, for consumption by multiple Investments applications and teams.

Maintaining and enhancing existing services, including those written in Python and Node.js, and driving their modernization where appropriate.

Improving service reliability, performance and observability through automated testing, telemetry, monitoring and alerting.

Providing support for production services and their consuming teams, including onboarding and API documentation.

Technical Excellence:

Performing as a domain expert across the software lifecycle (design, coding, testing, deployment, operations), leading significant pieces of development.

Leading code reviews and actively participating in providing feedback on others' designs and code.

Being accountable for technical debt in your own software, and for the long-term maintainability of the services you own.

Owning complex technical problems — breaking them down methodically, making tactical vs. strategic trade-offs, and adapting your approach as new information emerges.

Leadership:

Leading projects, work streams, or a small project team as required.

Mentoring and supporting team members, particularly junior developers, and actively suggesting improvements to team practices and engineering standards.

Business Knowledge:

Able to work directly with internal consumers, business partners, and technology teams.

Can articulate business needs and translate them into well-designed, reusable technology services.

Buy or sell side investment management domain knowledge (Equity, Fixed Income or Multi-Asset).

• AI-Assisted Development — Proficiency with modern AI tools (Claud, Copilot, etc.) to accelerate workflows and code quality.
• Security — Experience with authentication and authorization standards (OAuth2, OIDC, JWT) and secure service design.
• Messaging and Real-Time Data — Experience with Kafka, MQ or similar messaging platforms, or with WebSockets and streaming architectures.
• API Management — Experience with API gateways, documentation tooling (e.g. OpenAPI/Swagger) and developer onboarding for shared services.
